TPS60400DBVR Unregulated 60-mA Charge Pump Voltage Inverter. The TPS6040x family of devices generates an
unregulated negative output voltage from an input
voltage ranging from 1.6 V to 5.5 V. The devices are
typically supplied by a preregulated supply rail of 5 V
or 3.3 V. Due to its wide input voltage range, two or
three NiCd, NiMH, or alkaline battery cells, as well as
one Li-Ion cell can also power them.
Features :
- Inverts Input Supply Voltage
- Up to 60-mA Output Current
- Only Three Small 1-µF Ceramic Capacitors
